In 1661, the Duchy of Montferrat, a small but strategically significant state in northwestern Italy, operated within a complex and fragmented monetary landscape. As a possession of the Gonzaga dynasty of Mantua, its currency system was deeply intertwined with that of the Mantuan state, but it also reflected broader regional influences. The primary unit of account was the
lira (divided into 20
soldi and 240
denari), but the actual coins in circulation were a diverse mix. These included local issues from the Mantuan mint, such as
sesini and
trilline, alongside a heavy influx of foreign silver coins, particularly Spanish
reales and Piedmontese
scudi, due to Montferrat's location on the border of Spanish-controlled Milan and the Duchy of Savoy.
The period was one of significant monetary instability and debasement. The Mantuan state, under the financially strained Duke Charles II Gonzaga, frequently resorted to reducing the silver content in its coinage to raise short-term revenue. This practice, common across many Italian states during the 17th century, led to chronic inflation, a loss of public confidence in local currency, and the hoarding of older, purer coins. Consequently, the effective money supply in Montferrat was dictated more by the inflow and valuation of foreign specie than by local minting, creating a confusing system where exchange rates fluctuated and transactions required expert knowledge.
This monetary confusion was exacerbated by Montferrat's precarious political situation. Following the War of the Mantuan Succession (1628–1631), much of the duchy was under de facto French influence, though officially held by the Gonzaga. This political ambiguity meant monetary policy was often reactive rather than sovereign. The local economy, primarily agricultural, suffered from this instability, as taxes collected in debased coinage and prices in markets were difficult to stabilize. Thus, in 1661, Montferrat's currency situation was characterized by dependency, debasement, and disorder, mirroring the duchy's own vulnerable position amidst the competing powers of 17th-century Italy.
